![]() ![]() In the design window, design your report to appear how you want it to be. Anyway, let's get back to the task at hand. If you want to add a column to the data, just change the SQL query. Plus, you don't have to manage the report files individually. Also, it becomes very easy to standardize a report layout across any number of reports, and then change that standardization if your company updates their logo or decides to change their report look and feel. After the initial building of the classes, a reporting engine built on these principals could be re-used time and time again. What if your user has 30 different reports they want? Also, you would lose flexibility in the data source. That's a great solution if you only need one or two reports and don't mind managing each of them by hand. We could, in fact, create a DataSet object, add the tables and columns we need, hook up each field to reports we want, and have as many RDLCs in our project as reports that we need. If we are building a DataSet object, why don't we just connect it to the database, use it as our single source, and just add a new RDLC for each report? Well, that's a good question. Go ahead and add the DataSet we created as the data source. Along the left side, you should see a window where you can add a data source. Once you have your application, add a DataSet to the project. The type doesn't really matter, but for testing purposes, it is best to choose the type of application you are going to use the ReportViewer in. In Visual Studio 2005, create a new project. Reports can be as simple as tabular data, a chart, or a series of both, with images, logos, etc. To determine how the RDLC is generated, we have to create a sample. The simplest way is to use SQL Server 2005 installed with Reporting Services, but I found, with a little exploration, that the process of binding these two objects into the ReportViewer is flexible enough to support using any data source, if you don't mind a little elbow grease. Along with the RDLC file, the ReportViewer needs the actual data bound to it. rdlc file which serves as the template for both the data that is passed in and the formatting inside the ReportViewer. My first task in using the control was to determine how to actually go about using it. Both controls are only available for use in Microsoft Visual Studio 2005 or later and the. The second is in, and is designed to be used in ASP.NET. The first is located in the library, and is for Windows application development. It should be noted that there are two versions of the ReportViewer control. I initially discussed this topic on my blog, but decided CodeProject is a better location. A great feature about this control is the ability to save the report straight into Excel. When one of my clients asked for a reporting engine that allowed for dynamic reports - that is, user defined parameters define the data shown in the reports, I began to look at the ReportViewer control. ![]() There are so many ways to show reports - formatted HTML, GridViews, Repeaters - the list goes on and on and on. As developers, displaying reports is one thing we all spend a lot of time on. ![]()
